N-(pyridine-2-yl)amides in water from ketones and 2-aminopyridine via direct oxidative C–C bond cleavage has been developed. A series of ketones, including more challenging inactive aromaticketones substituted with diverse long-chain alkyl groups, were selectively converted to N-(pyridine-2-yl)amides. Furthermore, the protocol can be applied to aryl alkyl carbinols to afford the corresponding amides in moderate

A direct one-pot Cu-catalyzed biomimetic oxidation of methyl ketones to pharmaceutically important N-heterocyclic amides is reported. The scope of the method is broad, scalable, and mild, and the reaction is tolerant with various acid, base sensitive functionalities with multiple heteroatoms and aryl halides. The extensive mechanistic studies suggest that this reaction follows the Luciferin-Luciferase-like

The simple and inexpensive N,N-dimethylcyclohexane-1,2-diamine/CuI catalytic system provides a versatile, easy and efficient access to an array of N-(2-pyridin-2-yl)-amides from 2-chloro-pyridine derivatives.
A mild and green methodology for the construction of N‐(pyridine‐2‐yl)amides from alkylarenes and 2‐aminopyridine in one step was developed. Various alkylarenes were directly transformed into the corresponding N‐(pyridine‐2‐yl)amides through tandem C(sp3)–H bond activation/oxidative cyclization/C–C bondcleavage.
